CJ Takes the Jargon Out Of… OPEX
Revenue growth gets a lot of attention.
But revenue alone does not determine whether a business becomes more profitable.
The costs of running the organisation matter too.
That is where OPEX comes in.
OPEX stands for operating expenses. These are the day-to-day costs of operating, selling and supporting the business, such as sales and marketing, rent, salaries, insurance, software, utilities and travel.
For those who have seen him in my work, Count Jargon®, or CJ for short, is one of the characters from the Financial Storyverse®, the story-led learning world behind Once Upon a Balance Sheet: How to Make Better Decisions, Drive Growth and Increase Profits. He was created to take the jargon out of finance and business concepts without taking away the meaning.
CJ’s translation:
OPEX is money spent to keep the business running from one day to the next.
Why should leaders care?
Because OPEX affects operating profit.
A business may grow revenue and still earn less profit if selling and administrative expenses rise even faster.
The objective is not simply to cut OPEX.
Some operating expenses build capability, support customers, strengthen controls and enable future growth.
The real question is:
What is driving the spending, what value does it create, and how does it change as the business grows?
Revenue shows what the business brings in.
OPEX shows what it takes to keep the business running.
CJ’s takeaway:
OPEX is money spent in operating, selling and supporting the business. Managing it well means removing waste without removing the capabilities that create value.
What financial term would you like CJ to take the jargon out of next?
